Surfactants will diffuse in water and adsorb at interfaces between air and water or at the interface between oil and water, in the case where water is mixed with oil.
- the insoluble hydrophobic group may extend out of the bulk water phase, into the air or into the oil phase, while the water-soluble head group remains in the water phase.
- This alignment of surfactants at the surface modifies the surface properties of water at the water/air or water/oil interface. The exact choice and amount of surfactant will depend upon the final desired coating composition and such information is well known in the art.

Description
- This invention provides a process for the preparation of reactive, flexible, water-resistant hydroxyethylpyrrolidone methacrylate/glycidyl methacrylate copolymers. The copolymers may be covalently attached to active agents that are useful in a wide variety of compositions.
- The attachment of active agents to substrates using a variety of coating compositions is well known. A difficulty with the use of such compositions is that the active agents are leached from the substrates over time through a variety of means.
- Polyvinylpyrrolidone (PVP) is a non-toxic, ecologically friendly, water and organic soluble, film-forming stiff polymer (high Tg), which has excellent adhesion to a variety of substrates, such as metal, hair, skin, porcelain, plastics, polyesters, paper, concrete, and clays. The carbonyl group in polyvinylpyrrolidones has the ability to hydrogen bond/complex both high molecular weight entities such as polyphenols, tannins, polyacids and low molecular weight entities such as active pharmaceutical ingredients (as a drug excipient), inks or dye-mordants, and mycotoxins.
- Polyvinylpyrrolidone can be radical crosslinked by gamma-ray, x-ray, E-beam, UV-cured, and thermally activated by radical species to form an insoluble composite thereby rendering the PVP formulation as a hydrogel, or a surface treatment that is (semi)permanently affixed to the substrate on which it was coated. However, these crosslinking treatments require specialized equipment not readily available and the crosslinking conditions can damage other components in the formulation rendering them useless in the desired application.
- While the carbonyl oxygen atom in polyvinylpyrrolidone is a strong hydrogen bond accepter, access to the oxygen atom is hindered due to the close proximity of the oxygen atom in the polymeric backbone. Applicants have found that extending the polyvinylpyrrolidone group away from the polymeric backbone on a pendant group results in less steric hindrance and better access to the oxygen atom.

- The present disclosure provides reactive, flexible, water-resistant hydroxyethylpyrrolidone methacrylate/glycidyl methacrylate copolymers having the structure:
- According to the invention the polymerization process to prepare the copolymers is precipitation polymerization.
- The precipitation polymerization process of the present invention can provide the copolymer in a yield of 80% or more, preferably 90-98%, as a powder, which powder can be filtered and recovered easily.
- The reaction solvent in the precipitation polymerization process of the invention suitably is a C3-C10 saturated hydrocarbon which is branched or unbranched, cyclic or acyclic. Preferably the solvent is a C5-C8 aliphatic hydrocarbon or mixtures thereof.
- A preferred aliphatic hydrocarbon solvent over other known precipitation polymerization solvents is selected from acetone, hexane, ethyl acetate, heptane and cyclohexane. Acetone and cyclohexane are the most preferred solvents, provides high yields of a precipitate of the desired copolymer composition as a fine white powder which is easy to filter and dry.
- The amount of solvent used in the process of the invention should be sufficient to dissolve an appreciable amount of the reactants and to maintain the copolymer precipitate in a stirrable state at the end of the polymerization. Generally, up to about 40% solids, preferably 15-20% solids, is maintained in the reaction mixture to avoid the formation of large agglomerates/ "rocks".
- The precipitation polymerization process of the invention is carried out in the presence of a polymerization initiator, preferably a free radical initiator, and most suitably, a peroxy ester, e.g. t-butylperoxy pivalate, although other free radical initiators such as acylperoxides, alkyl peroxides, hydroperoxides, nitroxides, organometallics, persulfates, percarbonates, Type-I and Type-II-photo-initiators, peracids, thiocarbamates, azo-compounds, and azonitriles, known in the art, may be used as well.
- The amount of such initiator may vary widely; generally, about 0.2-5.0% is used, based on the weight of total monomers charged.
- The reaction temperature may vary widely; generally, the reactants are maintained at about 50°-150° C., preferably 60°-70° C., during the polymerization. Pressure usually is kept at atmospheric pressure, although higher and lower pressures may be used as well.
- The reaction mixture should be stirred vigorously under an inert atmosphere, e.g. nitrogen, during the polymerization. A stirring rate of about 400-600 rpm in a 1-liter lab reactor is quite adequate to effect the desired polymerization and to keep the precipitate in a stirrable state during the polymerization.
- The precipitation polymerization process of the invention may be carried out by first precharging a suitable reactor with a predetermined amount of hydroxyethylpyrrolidone methacrylate in the aliphatic hydrocarbon solvent, and heating the mixture to the desired reaction temperature while stirring vigorously under an inert gas atmosphere. The initiator is then charged into the reactor, and immediately a preselected amounts of glycidyl methacrylate and hydroxyethylpyrrolidone are added into the reactor over a period of time, generally about an hour or more. The reaction mixture then is held for an additional period of time for polymerization to occur. Finally, the slurry is cooled to room temperature. Filtering, washing with solvent, and drying provide the copolymer in yields approaching quantitative, and, substantially, in a composition predetermined by the weight ratio of monomers introduced into the reactor.
- Alternatively, the aliphatic hydrocarbon solvent can be precharged into the reactor, purged with nitrogen, heated to the reaction temperature, the initiator added, and then separate streams of the hydroxyethylpyrrolidone methacrylate and glycidyl methacrylate monomer are introduced over a period of time into the precharged reactor. Other process variations will be apparent to those skilled in the art.

Pharmaceutical applications include, but are not limited to, processing aids, medical stents, lubricity modification agents, catheters and other medical device coatings, active ingredient solubilizers, adhesive patches, optical lenses, formulating drug delivery systems, and preparing tablet coatings. - The polymer is suitable to modify the surface of active agents include; modified silicones, poly-dimethylsiloxane, hair-dyes, UV-filters, conditioning agents, vitamins, peptides, enzymes, microbiological agents, cleansing agents, fragrances, medical coatings or devices, pharmaceutical actives, oncology agents, therapeutic agents and therapeutic-peptides/polypeptides, pigments, dyes, colorants and inks, polymeric binders, formation of block-copolymers and hybrid-polymer compositions with other industrially significant polymers and copolymers such as (meth)acrylates and/or (meth)acrylamides, cellulosics, starches, polyesters, polyamides, vinyl-polymers, proteins, guar, poly-olefins and their chemically modified counterparts. Once the active agent is attached to the copolymer, the attachment provides a means to cross-link with other substrates and/or itself, so that it is (semi)permanently attached to the surface of the substrate by a covalent bond, that has a reactive nucleophilic or electrophilic atom within it, and/or can be encased by the crosslinked polymer-active matrix itself.
- Hair-dyes leach from dyed hair over time. The present copolymers can bind hair dyes to hair substrates through covalent bonds that cannot be leached. The present copolymers provide a means to react hair-dyes and printing dyes onto the present copolymers so that when they contain an inorganic or organic OH, SH, NH, or an acidic hydrogen like inorganic and organic acids, or active-hydrogen compounds like Michael-donors or acceptors, or any nucleophilic or electrophilic functionality capable of reacting with the epoxy-functionality, the hair and printing dyes will be permanently bonded to the copolymers. Upon further crosslinking, a crosslinked matrix of active agents and copolymers result in (semi)permanently fixed to the substrate in one step or multiple steps.
- When poly-dimethylsiloxane is mixed with an aqueous copolymer formulation, the dispersion formed phase-separates into an oily layer and an aqueous layer within minutes. However, when poly-dimethylsiloxane is reacted with the present copolymers, the terminal hydroxyl or amino-functionality of these modified silicones can attach to the epoxy functionality thereby making them more water dispersible and stable as micro-emulsions.
- Accordingly, the present disclosure also provides a universal surface modification composition, or delivery system, comprising the present copolymer. The present copolymer composition is reacted with useful actives and simultaneously or sequentially crosslinked onto a substrate under mild conditions. The disclosure also provides a means to decay the composition into a non-toxic glycerol entity, when not used or reacted with another agent so form environmentally friendly and green compositional by product results.
- According to one of the embodiment, the copolymer according to present disclosure is useful as an ingredient in coating compositions along with one or more polymeric binders, pigments, fillers, and surfactants.
- Polymeric binders, also referred to as emulsions, latexes, adhesives, glues, dispersions, or resins, are versatile systems in the construction and design of polymers. Examples of suitable binder classes include vinyl esters of versatic acid (VeoVa), styrene butadiene rubber (SBR) latex, styrene acrylate, polyvinyl alcohol and copolymers, polyvinyl acetate copolymers, vinyl acetate copolymers, carboxylated SBR latex, polyolefins and copolymer of polyolefins (i.e.; poly(ethylene-co-acrylic acid) and poly(ethylene-co-vinyl acetate)), styrene acrylate copolymers, styrene/butadiene/acrylonitrile, styrene/butadiene/acrylate/acrylonitrile, polyalkylene imines, polyvinyl pyrrolidone and copolymers, polyurethanes, polyamines, polyamides, cationic polyurethanes, polyethylene oxide, poly(2-ethyl-2-oxazoline), polyester resins, gelatins, casein, alginate, cellulose derivatives, hydroxyethyl cellulose, ethyl cellulose, hydroxypropyl cellulose, starches, ethoxylated, oxidized and enzyme converted starches, cationic starches, guar, cationic guar, water soluble gums, acrylic vinyl polymers, soy protein polymers as well as mixtures of water soluble and water-insoluble resins, latexes may be used. Latex binders are most commonly emulsions (polymer particles suspended in a liquid medium).
- Preferably, a binder is present in the coating compositions of the disclosure. A preferred binder is a vinyl acetate-ethylene copolymer, such as Vinnapas® 465 Emulsion, available from Wacker Chemie, AG. Vinnapas® 465 Emulsion is a rapid-setting vinyl acetate-ethylene copolymer, which is a high-solids emulsion. This emulsion combines a high-solids content with a low viscosity, which is a combination that permits the addition of high-filler loadings, resulting in adhesive formulations with solid contents of 80%, or more. Furthermore, this emulsion does not thicken excessively on the addition of plasticizers, which allows for the formulation of very high-solids adhesives. Vinnapas® 465 Emulsion also is shear stable, and can be applied on high-speed packaging machines using roll, extrusion, or spray equipment. The emulsion dries to a slightly tacky, clear, water-resistant film. Another preferred binder is Witcobond W-213 polyurethane dispersion, available from Uniroyal Chemical. Witcobond W-213 polyurethane dispersion is a waterborne, cationic dispersion from aliphatic urethanes. Strong, cohesive films can be produced simply by the evaporation of its water content. Witcobond W-213 polyurethane dispersion is used with cationic additives as a protective coating or surface treatment, where the properties of a light stable, waterborne urethane are suitable, primarily for textiles, nonwovens, fiberglass, paper, wood, urethane foam, or other porous substrates. The copolymer in coating compostion adheres well to various substrates such as polyester, poly(ethylene terephthalate), tempered aluminum foil and polystyrene.
- Preferably a pigment or pigments (colorant or colorants) are used in the coating compositions of the disclosure Suitable pigment materials are described in Hunger's "Industrial Organic Pigments," Itoh's "Dictionary of Pigments," and Leach and Pierce's "Printing Ink Manual." Pigment can be added by mixing components. Pigment or pigments may be added with a plasticizer and/or a filler. The exact choice and amount of pigment will depend upon the final desired coating composition and such information is well known in the art.
- Preferably a surfactant is used in the coating compositions of the disclosure. Surfactants (wetting agents, are compounds that lower the surface tension of a liquid, the interfacial tension between two liquids, or that between a liquid and a solid. Surfactants may act as detergents, emulsifiers, foaming agents, and dispersants. Surfactants are usually organic compounds that are amphiphilic, meaning they contain both hydrophobic groups and hydrophilic groups. Therefore, a surfactant contains both a water-insoluble (or oil-soluble) component and a water-soluble component. Surfactants will diffuse in water and adsorb at interfaces between air and water or at the interface between oil and water, in the case where water is mixed with oil. The insoluble hydrophobic group may extend out of the bulk water phase, into the air or into the oil phase, while the water-soluble head group remains in the water phase. This alignment of surfactants at the surface modifies the surface properties of water at the water/air or water/oil interface. The exact choice and amount of surfactant will depend upon the final desired coating composition and such information is well known in the art.
- Other suitable components for aqueous based coatings of this disclosure include silicates and silica gels, free radical initiators, aluminates and aluminas, N-vinyl-2-pyrrolidone, N-vinyl-caprolactam, other N-vinyl amides, 1-vinyl imidazole, 4-acryloyl morpholine, polyvinyl pyrrolidone, polyvinyl alcohol, acetoacetylated polyvinyl alcohol, oxygen scavengers, styrene/acrylate latexes, acrylic latexes, polyalkylene glycols, maleic anhydride-co-methyl vinyl ether polymers, polyalkylene imines, oxetanes, oxazolines, benzoxazines, polydi allyldialkylammonium chloride materials, starch, acrylated epoxides, glycidyl acrylate monomers, polyurethanes, acrylated oligomers of polyurethanes, acrylated glycidyl oligomers, polyfunctional acrylates, polyfunctional aziridines, clays, calcium carbonates, talcs, cellulosics, cycloaliphatic epoxides, vinyl ethers, epoxy based dispersions, anionic surfactants (i.e., sodium lauryl sulfate), non-ionic surfactants, cationic surfactants, silanes or silicone based polymers, and anionic polyacrylates, such as polyacrylic acid. Optional components in the composition for optimization of the coating composition when coated on different substrates include pigments, clays, e.g. organoclays and water-swellable clays, acrylic polymers, acrylic copolymers, alginates, carrageenan, microcrystalline cellulose, gelatin, carboxymethylcellulose sodium, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, methylcellulose, guar and guar derivatives, locust bean gum, polyethylene oxide, polyvinylpyrrolidones, copolymers of polyvinylpyrrolidones, polyvinylalcohols, charge control agents, optical brighteners, other water soluble polymers, silicas, aluminates, zirconates, calcium carbonates, xanthan gums, polymers or copolymers of water soluble vinyl lactams optionally having in situ-formed particles of crosslinked vinyl lactam polymers or copolymers, crosslinked polyvinyl pyrrolidone, and crosslinkers to achieve advantageous printable surface coatings having light stability (see
US 6,872,787 B2 ). Preferred components and optimal amounts of these components will depend upon the specific support coating and application and can be readily determined by one of ordinary skill in the art. - Colloidal silica, amorphous colloidal silica particles may be included, e.g. 20-150 nm. Preferred colloidal silicas are Silcron IJ-25 and IJ-50. Silica gels, amorphous colloidal silica particles, may also be included, e.g., 4-7 microns. A preferred silica gel is Silcron G 100.
- The present disclosure also relates to curing or cross-linking or polymerizing a polymerizable material carried out by any appropriate method known in the arts. Insight into curing and cross-linking technology is disclosed in "Thermosetting Polymers," J.P. Pascault et. al. (Marcel Dekker, New York, 2002). The polymerization of reactive solution comprising polymerizable polymer may be carried out by employing any of the methods disclosed in "Principles of Polymerization 4th edition," by George Odian (J. Wiley and Sons, Hoboken, New Jersey, 2004). The preferable techniques or methods employed by the present invention to polymerize the polymers would include UV-radiation, UV-LED, laser beam, electron beam, gamma irradiation, free-radical, cationic, anionic, thermal, exposure to e-beam and/or by employing a high-energy source in presence of suitable photo initiator for the initiation of polymerization. Suitable sources of radiation include, but are not limited to, mercury, xenon, halogen, carbon arc lamps, sunlight, and radioactive sources.
- Radical, thermal, or chemical crosslinking reactions obviate the problems and issues of high viscosity and uneven application of the crosslinked formulation and the disposal and cleaning of the non-biodegradable crosslinked copolymer formulations. When the unused or unreacted composition is simply exposed to water or moisture for several weeks, it renders the reactive epoxy-functionality into a stable non-toxic glycerol moiety so it is ecologically friendly to the environment.
- In order to induce polymerization via irradiation, photoinitiators are often incorporated to initiate the polymerization reaction system. Preferable photoinitiators are selected from the following non-limiting group or class of compounds such as 2-hydroxy-2-methyl-1-phenylpropane-1-one, 1-hydroxycyclohexyl phenyl ketone, and 2-methyl-1-[4-(methylthio)phenyl]-2-morphorinopropane-1-on; benzoins e.g. benzyl dimethyl ketal; benzophenones such as benzophenone, 4-phenylbenzophenone, and hydroxybenzophenone; thioxanthones such as isopropylthioxanthone and 2,4-diethylthioxanthone; acylphosphine oxides; and other special initiators such as methyl phenyl glyoxylate; bis[4-(di(4-(2-hydroxyethyl)phenyl)sulfonio)phenyl sulfide], a mixture of bis[4-diphenylsulfonio]phenyl)sulfide bis(hexafluoroantimonate and diphenyl-4-thiophenoxyphenylsulfonium hexafluoroantimonate, bis[4-(di(4-(2-hydroxyethyl)phenyl)sulfonio)phenyl sulfide], 5-2,4-cyclopentadiene-1-yl- [(1,2,3,4,5,6-.eta.)-(1-methylethyl-)benzene]-iron (1+)-hexafluorophosphate(1-)), 4-(2-hydroxytetradecanyloxy) diphenyliodonium hexafluoroantimonate, (4-hydroxynaphtyl) dimethylsulfonium hexafluoroantimonate), photo latent bases such as photo latent diazabicyclo nonene, triphenylsulfonium hexafluorophosphate, triphenylsulfonium hexafluoroantimonate, 4-methoxyphenyldiphenylsulfonium hexafluoroantimonate, 4-methoxyphenyliodonium hexafluoroantimonate, bis(4-tert-butylphenyl)iodonium tetrafluoroborate, (bis(4-tert-butylphenyl)iodonium hexafluorophosphate), (bis(4-tert-phenyl)iodonium hexafluoroantimonate), (bis[4-(diphenylsulfonio)phenyl]sulfide bis(hexafluorophosphate)), aryldiazonium salts, diaryliodonium salts, triaylsulfonium salts, triarylselenonium salts, dialkylphenacylsulfonium salts, triarylsulfoxonium salts, triethanol amine, aryloxydiarylsulfonium salts, and the like for example, triphenylsulfonium hexaflurophosphate, methyidiphenylsulfonium hexafluorophosphate, dimethylphenylsulfonium hexaflurophosphate, diphenyinapththylsulfonium hexaflurophosphate, di(methoxynapththyl)methylsulfonium hexaflurophosphate, (4-octyloxyphenyl) phenyl iodonium hexafluoro antimonate, (4-octyloxyphenyl) diphenyl sulfonium hexafluoro antimonate, (4-decyloxyphenyl) phenyl iodonium hexafluoro antimonite, (4-dodecyloxyphenyl)diphenyl sulfonium hexafluoroantimonate.

The photoinitiators may be used alone or in combinations thereof. Alternatively, the photoinitiator may be used by mixing it with one or more photopolymerization accelerator, such as a benzoic acid (e.g., 4-dimethylaminobenzoic acid) or a tertiary amine (e.g., diazabicyclo nonene (DBN)), in any appropriate ratio. The photoinitiator is preferably added to the photopolymerizable composition in the range of about 0.1% to about 20% by weight.
- The conditions of the thermal activation of the present copolymer, exposure to heat 90-230°C, can be achieved easily by a blow-dryer, flat-iron or curling-iron, or calendaring onto the substrate, do not destroy other useful ingredients in the formulation. The conditions for preparing the crosslinkable compositions are very mild and can be performed without the need for specialized equipment or dangerous radiation sources.
